and without causing the-sashes to project inwardly into the apartment. Another object of the invention is to providenovel'means wherebyacce'ss may be had readily to both sides of each sash, to wash the glass in the sashes. i

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains. V v I With the above and other objects in view which will appearfas thedescription -procoeds, the invention resides in the combination and arrangement oi parts and in the details of construction hereinafter. describedand claimed, it being understood that changes 0 in the precise embodiment of the invention herein disclosed, may be made within, the scope oi what is claimed, without departing from the spirit of theinvention.

In the drawings Figure 1 shows in elevation, a device constructcd in accordance with the invention, parts being in section; Figure 2 is a section on the line 22 of Figure 1, the sashes being 7 closed; Figure 3 is a section on the line 2-2 of Figure 1, the sashes being open; Figure 4 is section on the line 41 of Figure 1; Fig ure 5 is an elevation showing one of the tracks;

6 is a detail enlarged from Figure 4; i

" Figure 7 is a sectional view showing the lower track attendant parts.

The numeral 1 marks a frame comprising uprights 2, a lintel 3 and a sill 4. The sill i carries an inverted trough-shaped track 5,

' and there is a trouglrshape'd track (ion the lintel 3.

A first sash 7 is provided'and is mounted for right-line reciprocation 1n the direction 1" arrow A in Figure On its lower 0 2e edge, th first sash 7 has upstanding brackets a track 5. On its upper edge, the first sash 7 has depending brackets 9 engaged shdably with the upstanding flange of the track 6.

There are openings 10in the said flanges of the tracks 5 and 6, so that when the first sash 7 is pushed-to the right in Figure 3, in the direction of the arrow A, as far as the sash can go, the sash 7 then may be detached, in the direction of the arrow B in Figure 3, the

ends of the brackets Sand 9 passing outward- 1y through the openings 10.

n ged with the depending flange of they The numeral 12 designates a second sash which has a compoundmovement in the direc tion of the arrow. A of Figure 3 and in the direction of the arrow B. The sashes 12 and 7 are beveled on their inner vertical edges, as

at 14, to facilitate the relative movement of the sashes in the direction of the arrow B, the sashes being in the same plane, when they are in closed position. .7 are held in the same plane, and in a closed The sashes 12 and position, by a latch mechanism 15, of any (lo- 7 being adapted to cooperate with the guides 17.

On its lower portion, the sash 12 is provided edges of the sash 7, the said wear strips 20 i with a horizontally swinging latch 24 adapted r to cooperate with a keeper 25 on the sill 4.

latch 24 and the keeper 25 retaining the sash 12 in thejposition shown in Figure 3, the sash 7 abutting against the pivotal mounting of the latch 24, as indicated in Figure 3, to prevent the first sash from being slid any further to the right. Referring to Figure 3, it will be observed that there is ample space between the outer edges, of the sash 7 and of the sash 12, and the uprights 2, so that air can enter. It is to be observed that, in the opening of the sashes 7 and 12, it has not been necessary to I remove the screen 21 nor when the sashes are in the position shown in Figure 3, do they project inwardly into the apartment.

' When it is desired to wash the panes of the sashes 7 and 12 the screen 21 may be opened or removed. Then the sash 12 may be swung outwardly on its pivot elements 19 until the sash stands about at right angles to the sash 7 It will then be possible for an operator to have access to both sides of the sash l2, and to both sides or the sash 7 for the purpose of washing the anes. b

Although the device has been shown as embodying two sashes, it may consist or one sash, or more than two sashes.

hat is claimed is In a device of" the class described, a frame, a first sash. means for mounting the first sash for right-line sliding movement on the frame, a second sash alined with the first sash, means for mounting the second sash on nism forming a releasable connection be-.

tween the second sash and the frame, to limit all of the aforesaid movements of the second sash, the latch mechanism being interposed, in the path of the-first sash to stop the 'rightline sliding movement of the first sash when the first sash moves toward open position.

In testimony that I claim theforegoing as my own, I have hereto affixed my signature.
